Well it happened again. Car bogged down and cut off. No CEL this time. I looked at the data log and one Bank 1 sensor is a 1.xx volts while Bank 2 is 4.xx. Seems like the MAF is acting up. :shakes head:

At idle, both MAF sensors are reading .82. Once I get on the throttle and start to build boost is when the engine hits a wall and cuts out. At this point on the data log, the two sensors are reading very different from each other. Could it be that I have a big boost leak? I have included a screenshot of the two MAF Volt charts (you can see the difference). At one point, Bank 1 is reading 3.96v while Bank 2 is reading 1.27v. It is hard to see in the picture, but the Red and Green lines are the two MAF Volt plots.

so im in my driveway and did some quick, easy accelerations and you may have a boost leak or a vacuum leak. do you have a boost gauge or controller and have you tried the throttle body cleaner trick I told you? Also, do you have the MAF cleaner?

Im getting almost even voltage to each MAF in both banks and a lot of wheel spin :tup:. I need new rear tires :p

I stopped a little before 4,000rpm and was seeing 3.xx volts so im not really sure.

Also:

check your waste gate lines, BOV line, and all fitting to make sure they are still connected and no holes or anything of that nature are present in the lines.

This is one of those things where I wish the person was closer so I could just have them come over and help them finnd the problem. I really hope you find whats causing this and lmk if you need to know where the fittings are that you sould check.

I think your MAF sensor got wet especially if it was raining hard like you said in the email, clear the codes and look at both MAF voltages to see if they are even voltage wise. you Should see around.8 to .9 volt at idle . Rev the engine and see if the voltage is increasing smoothly. If all that is good then i think you got lucky and the sensor did not get damaged.

If the sensor got wet then there is a possibility that you might have still some water left in the intercooler, You should check and clean as needed .

Hope this help .

Well I took the MAF sensor out and it was wet. Guess water got in the system somehow. Any suggestions on getting everything dry? I guess I will pull the bumper and intercooler and check things out. I am guessing there is water in the intercooler.

You should have pulled that a long time ago when I mentioned dirty MAF but I hope it won't need replaced. Carefull with the MAF when cleaning/drying it, very sensative. I would just let it air try in a clean area. After it's dry, use MAF cleaner on it.

Im surprised water go into the system, I have driven in some bad wheather and I havent had that yet.... :/

Well I pulled the intercooler and it was full of water. Probably close to a gallon. It looks like the water was dripping in through the passenger side air filter and collecting in the charge piping. I really don't want this to happen every time the car sits in the rain. I am thinking about fabricating some sort of drip shield for that filter. Any thoughts?
